The Puffin Foundation is a private foundation that gives grants to left-of-center and arts-focused nonprofits. The Puffin Foundation was launched in 1983 by Perry Rosenstein.  The foundation primarily donates to apolitical charity groups, although its advocacy-related philanthropy has supported environmental and conservation groups in the Northeastern United States. The foundation has a sister organization called the Puffin Foundation West, which is based in Columbus, Ohio, and gives grants in the Southern and Midwestern United States.
